Abstract

In a process for the anionic polymerization of lactams having 5 to 14 ring members, the polymerization activator used is a compound of the general formula <FORM:1043678/C3/1> where n is 1 or 2, R1 and R2 are each monovalen hydrocarbon radicals having one to seven carbon atoms or R1 and R2 joined together form a divalent radical, R3 is hydrogen or a hydrocarbon radical having one to eight carbon atoms and R, when n is 1 is an alkyl amine, arylamino or aralkylamino radical having one to fourteen carbon atoms, and, when n is 2 is a divalent radical having the formula -NH-R3-NH- where R4 is a divalent hydrocarbon radical having two to fifteen carbon atoms. Specified lactams are pyrrolidone, piperidone, e -caprolactam, capryllactam, oenanthiclactam, capriclactam, laurolactam, e -ethyl-e -caprolactam, #x-ethyl-#x-oenantholactam and methylenebis-caprolactam. Fillers, e.g. glass fibres, asbestos, graphite, gypsum, chalk, molybdenum sulphide, wood flour and fibres may be incorporated into the polymerization mixture. In Examples (1) to (6), e -caprolactam is polymerized in the presence of sodium caprolactam and: (1) benzimidazole-1-carboxylic anilide; (2) imidazole-1-carboxylic acid N : N1-diphenyl amide; (3) benzimidazole-1-carboxylic acid (N1-methyl) anilide; (4) 2-methylimidazoline-N(1)-carboxylic acid N : N1-diphenyl amide; (5) N : N - hexamethylene - bis - (carbamyldimethyl formamidine) and (6) (a) hexamethylene - bis - (N1 - carbamyl - 2 - methylimidazoli (b) hexamethylene-bis-(N-carbamyltriphenyl formamidine). In Example (7) pyrrolidone is polymerized in the presence of sodium methylate and imidazole-1-carboxylic diphenylamide.
